I agree that music is a good analogy. For example, in the US there is a guy who has "shortcut" piano courses. His point is that yes, if you aspire to be a concert pianist, then you should spend years learning scales, reading music, and playing music from classical composers. But if you just want to play a few Billy Joel or Beatles songs, you can skip all that and cut to the chase. You won't have that great "foundation" needed to be a master player, but most people don't want that in the first place.
